A friendly 3D digital robot character named 'Vector' designed to help kids learn math. The robot is made of bright geometric shapes, with a cube-shaped head with rounded corners. Its face is a glowing digital screen showing friendly pixel eyes and a cheerful smile, with subtle mathematical symbols floating on the screen. Its body is a bright blue cylinder, and its arms and legs are glowing neon orange vector arrows. One of its hands is projecting a colorful, glowing 3D hologram of a geometric cone and a sphere. On its head, a small academic cap is tilted playfully. Pixar style, vibrant colors, clean educational background, soft studio lighting, cute and welcoming atmosphere.
